“…Another application is an indoor lighting system that can adjust building lights depending on the ambient light levels. In [160], Warmerdam et al simulate an LED lighting system of overhead building lights as VLC gateways that communicate with light sensors using LED/PD links. In this example, gateways are connected through wireless RF technology or ethernet.…”

<div>The continuous development of the Internet of Things (IoT) calls for innovative solutions and technologies to realize the IoT vision efficiently. One of the rising connectivity technologies that can potentially benefit the IoT deployment is Optical Wireless Communication (OWC) technology. In OWC, light beams from light sources are used to modulate information. The receiver demodulates the received light and processes the signal. The broad unlicensed spectrum of the OWC technology, along with its potential high bit-rate and increased physical link security, motivated researchers to consider OWC for IoT solutions. In this paper, we survey the existing literature related to using OWC technology in the IoT domain. We present the background and preliminaries of the IoT and OWC domains to understand how the OWC fits in the IoT architecture. Then we perform a comprehensive survey of literature related to the use of OWC technology in IoT applications. We highlight and summarize the major papers and experiments in the literature to provide researchers a jump-start to tap into the domain of OWC in IoT using the systemic and detailed survey presented in this paper.</div>

“…The VLC is in demand to realize the optical attocells network and become a new path towards the smaller cells [10]. Besides, the VLC system of multiple LED lighting was presented in an indoor ecosystem to connect several devices in short-range distances [11]. The visible light of the indoor transceiver system was investigated extensively.…”

Visible light communication VLC is deemed as futuristic technology applied for both illumination and data communication due to the low-cost energy consumption, long life expectancy, huge bandwidth, and high security compared to radio frequency RF. Uncovered area, minimum signal-to-noise ratio (SNR) and received power results from the non-uniform distribution of small base stations (i.e. Optical attocells) in the room. In this paper, the researchers propose a new LEDs distribution of five optical attocells configuration model in order to optimize the received power distribution and SNR at the center of the room for indoor VLC system. The optical attocells configuration in terms of received power to fill the uncovered area at the center of the room has been investigated. The simulation results showed that the proposed attocells configuration saved 24.9% of the transmitted power. Besides that, the whole room was covered uniformly. As a result, the received power and SNR are improved.

The communication using visible light is the new trend in communication field where the different coloured light or different intensity of light is used to communicate. Why the visible light communication is more important in this era? It is because the already existing communication method has some difficulties and interference. The most of the existing communication systems uses radio frequency. In radio communication, information's such as sound, images are carried by radio waves. But this Radio Frequency [RF] communication has some disadvantages. It suffers from interference and high latency issues and the RF communication requires a separate setup for transmission and reception of radio waves. For overcoming these limitations, a new method is adopted ie, Visible Light Communication [VLC].
